Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen einer Fluchtwegmarkierung für Flugzeuge und eine nach dem Verfahren hergestellte Fluchtwegmarkierung. The present invention relates to a method for producing an escape route marking for aircraft and to an escape route marking produced by the method.
Fluchtwegmarkierungen sind in Notfallsituationen, in denen die Stromversorgung nicht immer gewährleistet werden kann, von besonderer Bedeutung. Es ist bekannt zur Fluchtwegmarkierung in Flugzeugen, die auch als Notfallmarkierung bezeichnet wird, photolumineszente Streifen am Fußboden im Innenbereich des Flugzeugs anzuordnen. Photolumineszenz wird gelegentlich auch als Nachleuchten und/oder Phosphorisieren bezeichnet. Die sicherheitstechnischen Anforderungen sind beispielsweise in der Deutschen Industrie Norm DIN 67 510 spezifiziert. Die Streifen werden geradlinig auf dem Fußboden verlegt und weisen den Passagieren und der Besatzung im Notfall den Weg zu den Ausgängen und Notausstiegen. In der Vergangenheit haben sich bei der Ausgestaltung von Flugzeugen zunehmend photolumineszente Streifen durchgesetzt, da diese ausfallsicher sind und ohne Stromversorgung betrieben werden können. Escape route markings are of particular importance in emergency situations where the power supply can not always be guaranteed. It is known for escape route marking in aircraft, which is also referred to as emergency marking to arrange photoluminescent strips on the floor in the interior of the aircraft. Photoluminescence is sometimes referred to as afterglow and / or phosphorizing. The safety requirements are specified, for example, in the German industrial standard DIN 67 510. The strips are laid in a straight line on the floor and, in an emergency, direct the passengers and the crew to the exits and emergency exits. In the past, photoluminescent strips have increasingly prevailed in the design of aircraft, since they are fail-safe and can be operated without a power supply.
Aus WO 96/33093 AI ist beispielsweise eine Notfallbeleuchtung bekannt, bei der ein photolumineszenter Streifen in einem transparenten Trägerelement angeordnet ist. Das Trägerelement kann dabei ein-, zwei- oder dreistückig ausgebildet sein. Jedes Trägerelement besitzt eine langgestreckte rechteckige Form und kann dementsprechend in einer 90°- und 180°-Orientierung zu einem anderen Trägerelement verlegt werden. From WO 96/33093 AI, for example, an emergency lighting is known in which a photoluminescent strip is arranged in a transparent support member. The carrier element can be formed in one, two or three pieces. Each support member has an elongate rectangular shape and accordingly can be laid in a 90 ° and 180 ° orientation to another support member.
Aus WO 94/17766 AI ist eine photolumineszente Reflektorschicht bekannt. Es wird vorgeschlagen, aus dem flächigen Material längliche Streifen herzustellen. From WO 94/17766 Al a photoluminescent reflector layer is known. It is proposed to produce elongated strips from the sheet material.
BESTÄTIGUNGS OPK Aus US 4,401,050 ist eine photolumineszente Fluchtwegmarkierung bekannt, die aus länglichen Streifen besteht.

Gegenwärtig ist festzustellen, dass die Anforderungen an die Gestaltung bei der Möblierung des Fluggastinnenraums sich ändern. Insbesondere geht ein Trend dahin, nicht länger rechtwinklige Möbel vorzusehen, sondern auch geschwungene Möbelkonturen einzusetzen. Neben der ästhetischen Wirkung einer geschwungenen Möblierung, beispielsweise Sitzbänken mit geschwungener Außenkontur, Schränke und Theken im Servicebereich, besitzen geschwungene Möbel auch sicherheitstechnische Vorzüge, da die Passagiere sich beispielsweise weniger leicht verletzen können. Die zunehmend aufwendiger gestaltete Möblierung inklusive ihres Polsterdesign in dem Passagierraum macht es notwendig, auch die Fluchtwegmarkierung flexibel in der Form anpassen zu können. At present it is clear that the design requirements for the furnishing of the passenger compartment are changing. In particular, there is a trend to no longer provide rectangular furniture, but also to use curved furniture contours. In addition to the aesthetic effect of a curved furniture, such as benches with curved outer contour, cabinets and counters in the service area, curved furniture also have safety advantages, as the passengers, for example, less likely to injure. The increasingly elaborate furniture including its upholstery design in the passenger compartment makes it necessary to be able to flexibly adapt the escape route marking as well.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen einer Fluchtwegmarkierung und eine mit dem Verfahren hergestellte Fluchtwegmarkierung bereitzustellen, das bzw. die mit einfachen Mitteln an unterschiedliche Anforderungen bei Gestaltungen im Passagierraum eines Flugzeugs in der Form anpassbar sind. It is an object of the present invention to provide a method for producing an escape route marking and an escape route marking produced by the method, which can be adapted in simple form to different requirements in designs in the passenger compartment of an aircraft in the form.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren zum Herstellen einer Fluchtwegmarkierung gemäß Anspruch 1 und einer mit dem erfindungsgemäßen Verfahren hergestellten Fluchtwegmarkierung gemäß Anspruch 1 1 gelöst. Vorteilhafte Ausgestaltungen bilden jeweils die Gegenstände der Unteransprüche. According to the invention, the object is achieved by a method for producing an escape route marking according to claim 1 and an escape route marking produced by the method according to the invention according to claim 11. Advantageous embodiments each form the subject of the dependent claims.
Das erfindungsgemäße Verfahren zum Herstellen einer Fluchtwegmarkierung sieht die Verwendung einer erwärmbaren und verformbaren Stützform vor. Das Verfahren zur Herstellung umfasst folgende Schritte: Die erwärmbare und verformbare Stützform wird bereitgestellt, so dass ein Trägerelement in die Stützform eingebracht werden kann. Ein photolumineszentes Material und eine lichtdurchlässige Abdeckung werden auf dem Trägerelement in der Stützform angeordnet. Nach Anordnungen der Fluchtwegmarkierung mit ihren verschiedenen Schichten in der Stützform wird die Stützform zusammen mit der Fluchtwegmarkierung erwärmt und bevorzugt anschließend an die Erwärmung verformt. In der verformten Position erstarrt die Fluchtwegmarkierung in der Stützform. Durch Verwendung einer Stützform, welche einerseits den thermischen Veränderungen gegenüber widerstandsfähig ist und andererseits gut verformbar ist, kann die Herstellung der Fluchtwegmarkierung wesentlich vereinfacht werden. Durch Verwendung der Stützform können die aufeinander angeordneten Teile der Fluchtwegmarkierung sich nur unwesentlich zueinander verrücken, wodurch die Herstellung schneller und passgenauer durchgeführt werden kann. Eine mit dem erfindungsgemäßen Verfahren hergestellte Fluchtwegmarkierung ist auf dem Fußboden eines Flugzeuges und/oder entlang der Konturen des Mobiliars im Flugzeug verlegbar. Das photolumineszente Material der Fluchtwegmarkierung zeigt im Notfall den Passagieren und der Besatzung den kürzesten Weg zu einem Notausgang. Die Fluchtwegmarkierungen lassen sich ferner in die Ästhetik der Innenausstattung des Flugzeuges besser integrieren, ohne die sicherheitstechnischen Anforderungen zu beeinträchtigen. The method according to the invention for producing an escape route marking provides for the use of a heatable and deformable support form. The manufacturing process comprises the following steps: The heatable and deformable support form is provided so that a support member can be introduced into the support mold. A photoluminescent material and a translucent cover are placed on the support member in the support mold. After arranging the escape route marking with its various layers in the support form, the support mold is heated together with the escape route marking and preferably subsequently deformed to the heating. In the deformed position, the escape route marker solidifies in the support form. By using a support mold which on the one hand is resistant to thermal changes and on the other hand is well deformable, the production of the escape route marking can be substantially simplified. By using the support form, the parts of the escape route marking arranged on top of one another can only shift slightly relative to one another, as a result of which the production can be carried out more quickly and accurately. An escape route marking produced by the method according to the invention can be laid on the floor of an aircraft and / or along the contours of the furniture in the aircraft. The escape route marker's photoluminescent material shows passengers and crew the shortest route to an emergency exit in an emergency. The escape route markings can also be better integrated into the aesthetics of the interior of the aircraft, without affecting the safety requirements.
In einer zweckmäßigen Ausgestaltung des Verfahrens werden das photolumineszente Material und die lichtdurchlässige Abdeckung auf dem Trägerelement übereinander in der Stützform angeordnet oder diese werden bereits aufeinander angeordnet in die Stützform eingebracht. In an expedient embodiment of the method, the photoluminescent material and the translucent cover are arranged one above the other in the support form on the support element or these are already arranged one above the other in the support form.
Besonders bevorzugt werden Stützformen verwendet, die aus Silikon gefertigt sind, wobei nach dem Erstarren in der Stützform die Stützform in ihre nicht verformte Ausgangslage zurückkehrt und die Fluchtwegmarkierung in ihrer verformten Position verbleibt. Silikonformen sind besonders resistent, als auch flexibel verformbar und zugleich ausreichend robust. Ferner ist ein aneinander Haftenbleiben der aufeinander angeordneten Schichten an der Silikonform aufgrund der Eigenschaften des Silikons ausgeschlossen. Dadurch, dass die Stützform nach dem Erstarren in ihre nicht verformte Ausgangslage zurückkehrt, kann die Stützform für die Herstellung weiterer Fluchtwegmarkierungen wiederverwendet werden, wodurch eine solche Stützform ökonomisch einsetzbar ist. Particularly preferred support forms are used, which are made of silicone, wherein after solidification in the support form, the support form in their non-deformed Initial position returns and the escape route marker remains in its deformed position. Silicone molds are particularly resistant, as well as flexibly deformable and at the same time sufficiently robust. Furthermore, adhesion of the layers arranged on one another to the silicone mold is prevented due to the properties of the silicone. Due to the fact that the support form returns to its undeformed starting position after solidification, the support form can be reused for the production of further escape route markings, as a result of which such a support form can be used economically.
Gemäß einer besonders bevorzugten Ausgestaltung des Verfahrens wird die Fluchtwegmarkierung in der Stützform zunächst in der Stützform erwärmt und zum Verformen und/oder Erstarren in eine Erstarrungsvorrichtung angeordnet. Die Erstarrungsvorrichtung ist zur Unterstützung der Stützform vorgesehen und erlaubt es, die aufeinander angeordneten Teile in der Stützform gleichmäßig fixiert auskühlen zu lassen. According to a particularly preferred embodiment of the method, the escape route marking in the support form is first heated in the support mold and arranged for deformation and / or solidification in a solidification device. The solidification device is provided to support the support form and allows to let the superimposed parts in the support form evenly frozen cool.
In einer zweckmäßigen Ausgestaltung des Verfahrens ist die Erstarrungsvorrichtung als eine vorgefertigte Erstarrungsform vorgesehen. Die vorgefertigte Erstarrungsform ist im Vergleich zur Stützform stabiler und im Wesentlichen nicht verformbar. Eine geringe Elastizität der Erstarrungsform ist für das Anordnen der erwärmten Stützform in die Erstarrungsform von Vorteil. In an expedient embodiment of the method, the solidification device is provided as a prefabricated solidification mold. The preformed solidification mold is more stable and substantially non-deformable compared to the support mold. A low elasticity of the solidification mold is advantageous for placing the heated support mold in the solidification mold.
Eine andere zweckmäßige Ausgestaltung sieht vor, dass die Erstarrungsvorrichtung als eine Umformvorrichtung mit einer Steuereinheit ausgebildet ist. Eine mit einer Steuereinheit ausgebildete Umformvorrichtung ist vorzugsweise programmierbar, wodurch beliebige Verformungen über die Steuereinheit eingestellt werden können. Zu einer besseren Handhabung der Verformung ist bevorzugt vorgesehen, dass die Umformungsvorrichtung eine Vielzahl an parallel angeordneter Stäbe aufweist, welche durch die Steuereinheit entlang ihrer Längsrichtung verschiebbar sind, um die Fluchtwegmarkierung in die vorbestimmte Position zu bringen. Die Verwendung einer Vielzahl an parallel angeordneter Stäbe erlaubt es, individuelle Verformungen der Stützform und der darin angeordneten Fluchtwegmarkierung herbeizuführen. Auch das Einsetzen der Stützform in die Umformungsvorrichtung wird wesentlich vereinfacht, indem die Stäbe entlang ihrer Längsrichtung zunächst über die Steuereinheit zurückgefahren werden, so dass die Stützform bequem einsetzbar ist. Another expedient embodiment provides that the solidification device is designed as a forming device with a control unit. A formed with a control unit forming device is preferably programmable, whereby any deformations can be adjusted via the control unit. For better handling of the deformation, it is preferably provided that the transformation device has a plurality of parallel arranged rods, which are displaceable by the control unit along its longitudinal direction, to bring the escape route marking in the predetermined position. The use of a plurality of rods arranged in parallel makes it possible to bring about individual deformations of the support form and the escape route marking arranged therein. Also, the insertion of the support form in the forming device is substantially simplified by the rods are first moved back along its longitudinal direction via the control unit, so that the support mold is convenient to use.
In einer zweckmäßigen Ausgestaltung des Verfahrens werden erst nach dem Einsetzen der erwärmten Stützform die Stäbe in die die Verformung bildende bestimmte Position verfahren, so dass die erwärmte Stützform inklusive der darin angeordneten Fluchtwegmarkierung auskühlen und letztere erstarren kann. Nach dem Erstarren können die Stäbe der Umformungsvorrichtung aus ihrer Verformungsposition in eine Position überführt werden, die es erlaubt, die Stützform und die in der Stützform erstarrte Fluchtwegmarkierung einfach aus der Umformungsvorrichtung zu entnehmen. In an expedient embodiment of the method, the rods are moved into the specific position forming the deformation only after the onset of the heated support form, so that the heated support form including the escape route marking arranged therein can cool down and the latter solidify. After solidification, the rods of the forming device can be transferred from its deformation position to a position that allows to easily remove the support form and the solidified in the support form escape route marker from the forming device.
Eine weitere Ausgestaltung des Verfahrens sieht vor, dass die lichtdurchlässige Abdeckung einen thermisch verformbaren Kunststoff, bevorzugt Polycarbonat, umfasst. Polycarbonate sind Kunststoffe, die sowohl eine Glasübergangstemperatur als auch eine Schmelztemperatur besitzen. Unterhalb der Glasübergangstemperatur, auch Erweichungstemperatur genannt, befindet sich die amorphe Phase des Polycarbonats in einem erstarrten Zustand, während sich oberhalb der Glasübergangstemperatur das Polycarbonat in einem gummielastischen Zustand befindet. Im gummielastischen Zustand liegt das Polycarbonat erweicht vor und kann entsprechend verformt werden. Bei Temperaturen oberhalb der Schmelztemperatur liegt das Polycarbonat in einer flüssigen Phase vor, in der es vorzugsweise mit Farbpigmenten oder anderen Substanzen vermischt werden kann. Polycarbonate sowie andere Kunststoffe können folglich einerseits in einem Temperaturbereich besonders gut mit anderen Substanzen vermischt werden und in einem anderen Temperaturbereich thermisch verformt werden. A further embodiment of the method provides that the translucent cover comprises a thermally deformable plastic, preferably polycarbonate. Polycarbonates are plastics which have both a glass transition temperature and a melting temperature. Below the glass transition temperature, also called softening temperature, the amorphous phase of the polycarbonate is in a solidified state, while above the glass transition temperature, the polycarbonate is in a rubber-elastic state. In the rubber-elastic state, the polycarbonate is softened and can be deformed accordingly. At temperatures above the Melting temperature, the polycarbonate is in a liquid phase in which it can be preferably mixed with color pigments or other substances. Polycarbonates and other plastics can consequently be mixed particularly well with other substances in one temperature range and thermally deformed in another temperature range.
Gemäß einer weiteren Ausgestaltung des Verfahrens sind das Trägerelement und/oder das photolumineszente Material und/oder die lichtdurchlässige Abdeckung jeweils alleine oder zusammen aufeinanderliegend thermisch verformbar. Thermisch verformbare Materialien sind individuell verformbar, wodurch sie den Konturen des Mobiliars im Innenraum eines Flugzeuges einfacher und besser angepasst werden können. Werden das Trägerelement und/oder das photolumineszente Material und/oder die lichtdurchlässige Abdeckung zusammen aufeinanderliegend thermisch verformt, können mögliche Verschiebungen der Schichten untereinander oder zueinander vermieden werden. According to a further embodiment of the method, the carrier element and / or the photoluminescent material and / or the translucent cover are each thermally deformable alone or together. Thermally deformable materials are individually deformable, making them easier and better adapted to the contours of the furniture in the interior of an aircraft. If the carrier element and / or the photoluminescent material and / or the translucent cover are thermally deformed one upon the other, possible displacements of the layers with one another or with one another can be avoided.
Die Fluchtwegmarkierung hergestellt mit dem erfindungsgemäßen Verfahren weist eine lichtdurchlässige Abdeckung und ein photolumineszentes Material auf. Eine solche Fluchtwegmarkierung ist auf dem Fußboden und/oder entlang der Konturen des Mobiliars im Flugzeug verlegbar. Das photolumineszente Material der Fluchtwegmarkierung zeigt im Notfall den Passagieren und der Besatzung den kürzesten Weg zu einem Notausgang. Erfindungsgemäß weist die lichtdurchlässige Abdeckung Farbpigmente auf, welche zu einer lichtdurchlässigen Einfärbung der Fluchtwegmarkierung führen. Die lichtdurchlässige Abdeckung kann durch die Farbpigmente farblich dem Mobiliar im Flugzeug angepasst werden, wodurch die Fluchtwegmarkierungen sich in die Ästhetik der Innenausstattung des Flugzeuges besser integrieren lassen, ohne die sicherheitstechnischen Anforderungen zu beeinträchtigen. Ferner können für unterschiedliche Innenausstattungen verschiedener Flugzeuge unterschiedlich farbige Farbpigmente eingesetzt werden, so dass die lichtdurchlässigen Abdeckungen der Fluchtwegmarkierungen entsprechend angepasst werden können. Bei aus dem Stand der Technik bekannten Fluchtwegmarkierungen, die farblich angepasst waren, konnten diese nicht ohne weiteres verformt werden, da auf den Leuchtstreifen beispielsweise Folienstreifen angeordnet wurden. Beim Verformen eines solchen Folienstreifens wäre die Folie zerknittert oder sogar eingerissen. The escape route marking produced by the method according to the invention has a light-permeable cover and a photoluminescent material. Such an escape route marking can be laid on the floor and / or along the contours of the furniture in the aircraft. The escape route marker's photoluminescent material shows passengers and crew the shortest route to an emergency exit in an emergency. According to the invention, the translucent cover has color pigments which lead to a light-permeable coloring of the escape route marking. The translucent cover can be color-matched by the color pigments to the furniture in the aircraft, whereby the escape route markings can be better integrated into the aesthetics of the interior of the aircraft, without affecting the safety requirements. Furthermore, for different interiors different colored differently colored pigments are used, so that the translucent covers the escape route markers can be adjusted accordingly. In known from the prior art escape route markers that were color matched, they could not be readily deformed, as on the luminescent strips, for example, foil strips were arranged. When deforming such a film strip, the film would be crumpled or even torn.
In einer bevorzugten Ausgestaltung weist die Fluchtwegmarkierung mindestens einen nicht linearen Streckenabschnitt mit einem oder mehreren Radien auf. Fluchtwegmarkierungen mit nicht linearen Streckenabschnitten können in Bögen und Kurven verlaufen. Hierdurch kann die Fluchtwegmarkierung individuell an die Ausgestaltungen des Flugzeuginnenraums angepasst werden und dabei vorgegebene Konturen, insbesondere des Mobiliars, folgen. Mit nicht linearen Streckenabschnitten werden streifenförmige Abschnitte der Fluchtwegmarkierung bezeichnet, die in der Ebene, in der sie verlegt sind, sich nicht gradlinig erstrecken, sondern einen Bogen beschreiben. In a preferred embodiment, the escape route marking has at least one non-linear route section with one or more radii. Escape route markings with non-linear sections can run in bends and curves. In this way, the escape route marking can be individually adapted to the configurations of the aircraft interior and thereby follow predetermined contours, in particular the Mobiliars. Non-linear sections are strip-shaped sections of the escape route marking referred to, which do not extend straight in the plane in which they are laid, but describe an arc.
Gemäß einer Ausgestaltung weist die Fluchtwegmarkierung mindestens einen geschwungenen Abschnitt mit einander entgegengesetzten Krümmungen auf. Die mit dem erfindungsgemäßen Verfahren hergestellte Fluchtwegmarkierung ist mit entgegengesetzten Krümmungen insbesondere mit linksgekrümmten und rechtsgekrümmten Abschnitten herstellbar, wodurch beliebig gebogene Fluchtwegmarkierungen mit glatten Übergängen entstehen. Bedingt durch die entgegengesetzten Krümmungen weisen geschwungene Abschnitte entlang ihrer Kontur einen Wendepunkt auf, an dem eine Rechts- oder Linkskrümmung in eine Links- bzw. Rechtskrümmung übergeht. Gemäß einer bevorzugten Ausgestaltung weist die lichtdurchlässige Abdeckung einen thermisch verformbaren Kunststoff, bevorzugt Polycarbonat, auf. Polycarbonate sind Kunststoffe, die sowohl eine Glasübergangstemperatur als auch eine Schmelztemperatur besitzen. Unterhalb der Glasübergangstemperatur, auch Erweichungstemperatur genannt, befindet sich die amorphe Phase des Polycarbonats in einem erstarrten Zustand, während sich oberhalb der Glasübergangstemperatur das Polycarbonat in einem gummielastischen Zustand befindet. Im gummielastischen Zustand liegt das Polycarbonat erweicht vor und kann entsprechend verformt werden. Bei Temperaturen oberhalb der Schmelztemperatur liegt das Polycarbonat in einer flüssigen Phase vor, in der es vorzugsweise mit Farbpigmenten vermischt werden kann. Polycarbonate können folglich einerseits in einem Temperaturbereich besonders gut eingefärbt werden und in einem anderen Temperaturbereich thermisch verformt werden. According to one embodiment, the escape route marking has at least one curved section with opposing curvatures. The escape route marking produced by the method according to the invention can be produced with opposite curvatures, in particular with left-curved and right-curved sections, whereby any curved escape route markings with smooth transitions arise. Due to the opposite curvatures, curved sections along their contour have a turning point at which a right or left curvature changes into a left or right curvature. According to a preferred embodiment, the light-permeable cover has a thermally deformable plastic, preferably polycarbonate. Polycarbonates are plastics which have both a glass transition temperature and a melting temperature. Below the glass transition temperature, also called softening temperature, the amorphous phase of the polycarbonate is in a solidified state, while above the glass transition temperature, the polycarbonate is in a rubber-elastic state. In the rubber-elastic state, the polycarbonate is softened and can be deformed accordingly. At temperatures above the melting temperature, the polycarbonate is in a liquid phase in which it can preferably be mixed with color pigments. Consequently, on the one hand, polycarbonates can be dyed particularly well in one temperature range and thermally deformed in another temperature range.
In einer bevorzugten Ausgestaltung ist das photolumineszente Material in Form von Streifen mit einer Länge und einer Breite vorgesehen, die den Abmaßen der lichtdurchlässigen Abdeckung entsprechen. Die photolumineszenten Streifen können beispielsweise photolumineszente Pigmente aufweisen, die in einer Polymermatrix, bevorzugt in einer Silikon- oder Polycarbonatmatrix, eingebunden sind. In a preferred embodiment, the photoluminescent material is provided in the form of strips having a length and a width corresponding to the dimensions of the translucent cover. The photoluminescent strips may comprise photoluminescent pigments, for example, which are incorporated in a polymer matrix, preferably in a silicone or polycarbonate matrix.
Gemäß einer bevorzugten Ausgestaltung ist auf oder in einem Trägerelement das photolumineszente Material in Form eines den Abmaßen des Trägerelements entsprechenden Streifens und darauf die lichtdurchlässige Abdeckung angeordnet. Die lichtdurchlässige Abdeckung bietet somit einen Schutz für das photolumineszente Material vor Beschädigungen und Feuchtigkeit. In einer zweckmäßigen Ausgestaltung der Fluchtwegmarkierung ist eine Grundfläche des Trägerelements rechteckig ausgebildet, wobei sich entlang jeder Begrenzung der Grundfläche Seitenwände mit einer Dicke D in einem Winkel zu der Grundfläche erstrecken, wodurch eine Ausnehmung in dem Trägerelement gebildet ist. Bevorzugt stehen die Seitenwände senkrecht zu der Grundfläche. In einer solchen Ausnehmung kann ein photolumineszentes Material sicher vor Verrutschen platziert werden. According to a preferred embodiment, the photoluminescent material is arranged on or in a carrier element in the form of a strip corresponding to the dimensions of the carrier element, and the light-permeable cover is arranged thereon. The translucent cover thus provides protection for the photoluminescent material from damage and moisture. In an expedient refinement of the escape route marking, a base area of the carrier element is rectangular, with side walls with a thickness D extending along each boundary of the base area at an angle to the base area, whereby a recess is formed in the carrier element. Preferably, the side walls are perpendicular to the base. In such a recess, a photoluminescent material can be safely placed against slipping.
In einer zweckmäßigen Ausgestaltung der Fluchtwegmarkierung weist die lichtdurchlässige Abdeckung eine rechteckige Grundfläche auf, die in einem Abstand von der Begrenzung der Grundfläche sich in einem Winkel erstreckende Vorsprünge in Form von Seitenwänden mit einer Dicke D' aufweist, wobei die Vorsprünge so ausgebildet sind, dass ihre Außenseiten an den Innenseiten der Seitenwände des Trägerelements anliegen und zwischen lichtdurchlässiger Abdeckung und Trägerelement ein Hohlraum zur Aufnahme des photolumineszenten Materials gebildet wird, wenn die lichtdurchlässige Abdeckung auf dem Trägerelement aufgesetzt ist. In an expedient refinement of the escape route marking, the translucent cover has a rectangular base surface which has projections extending in an angle in the form of sidewalls with a thickness D 'at a distance from the boundary of the base surface, the projections being designed such that their projections Outer sides abut against the inner sides of the side walls of the support member and between the transparent cover and the support member, a cavity for receiving the photoluminescent material is formed when the translucent cover is placed on the support member.
Gemäß einer bevorzugten Ausgestaltung der Fluchtwegmarkierung sind die lichtdurchlässige Abdeckung und das Trägerelement als einstückiges Hohlprofil ausgebildet. Ein photolumineszenter Leuchtstreifen kann dann in das Hohlprofil eingebracht werden, bevorzugt durch Einspritzen oder Eingießen einer Silikon- oder Polycarbonatmasse, in der die photolumineszenten Pigmente eingearbeitet sind. According to a preferred embodiment of the escape route marking, the translucent cover and the carrier element are formed as a one-piece hollow profile. A photoluminescent light strip can then be introduced into the hollow profile, preferably by injecting or pouring a silicone or polycarbonate composition in which the photoluminescent pigments are incorporated.

Fluchtwegmarkierung.  An escape route marking.
Fig. 1 zeigt eine Fluchtwegmarkierung 1 in gerader Form mit einer eingefärbten lichtdurchlässigen Abdeckung 6. Unter der eingefärbten lichtdurchlässigen Abdeckung 6 ist ein nachleuchtendes, photolumineszentes Material 8 angeordnet, das wiederum auf einem Trägerelement 4 flächig aufliegend angeordnet ist. Das photolumineszente Material ist gemäß Fig. 1 in einem transparenten Trägerelement vorgesehen. Das Trägerelement kann transparent ausgebildet, kann aber auch nicht durchscheinend ausgebildet sein, wenn es im verlegten Zustand der Fluchtwegmarkierung mit dem Untergrund verbunden ist. Alternativ kann das photolumineszente Material auch in das transparente Trägerelement eingegossen sein. Das photolumineszente Material kann dann beispielsweise aus photolumineszenten Pigmenten bestehen, die in einer Polymermatrix, bevorzugt einer Silikon- oder Polycarbonatmatrix, eingebunden sind. Fig. 1 shows an escape route marker 1 in a straight shape with a colored translucent cover 6. Under the colored translucent cover 6 a luminescent, photoluminescent material 8 is arranged, which in turn is arranged lying flat on a support member 4. The photoluminescent material is provided according to FIG. 1 in a transparent carrier element. The support member may be transparent, but may also not be translucent, if it is connected in the installed state of the escape route marking to the ground. Alternatively, the photoluminescent material may also be cast into the transparent support member be. The photoluminescent material may then consist, for example, of photoluminescent pigments incorporated in a polymer matrix, preferably a silicone or polycarbonate matrix.
Fig. 2 zeigt eine Querschnittsdarstellung der Fluchtwegmarkierung gemäß Fig. 1. In dem Querschnitt ist zu erkennen, dass das Trägerelement 4 eine Ausnehmung 5 aufweist, in die das photolumineszente Material 8 eingesetzt ist. Gemäß Fig. 2 sind die Abmaße des photolumineszenten Materials 8 geringfügig kleiner als die Ausnehmung 5 des Trägerelements 4 ausgebildet, so dass seitlich eine sich in Längsrichtung erstreckende Fuge ergibt, in die die Seitenwände der Abdeckung eintauchen. Eine Abdeckung 6 ist auf das photolumineszente Material 8 aufgebracht und schließt seitlich mit dem Rand des Trägerelements 4 ab. Die Fugen zwischen den Rändern der photolumineszenten Materials 8 und den Rändern der Ausnehmung 5 sind mit den Vorsprüngen der Abdeckung 6 aufgefüllt. Alternativ kann das photolumineszente Material 9 passgenau auf die Ausnehmung 5 des Trägerelements 4 zugeschnitten sein. Bei dieser Alternative weist die rechteckförmige Abdeckung keine Vorsprünge auf, sondern ist beispielsweise mit dem Trägerelement verklebt oder verschweißt. Das Verkleben oder Verschweißen von Abdeckung und Trägerelement kann durchgeführt werden bevor oder nachdem ein Leuchtstreifen in das Trägerelement angeordnet wurde. Wird der Leuchtstreifen erst nach dem Verkleben oder Verschweißen in das aus Abdeckung und Trägerelement gebildete Hohlprofil eingebracht, kann dies vorzugsweise durch Einbringen einer die photolumineszenten Pigmente enthaltende Silikon- oder Polycarbonatmasse geschehen. 2 shows a cross-sectional view of the escape route marking according to FIG. 1. It can be seen in the cross section that the carrier element 4 has a recess 5 into which the photoluminescent material 8 is inserted. According to FIG. 2, the dimensions of the photoluminescent material 8 are slightly smaller than the recess 5 of the carrier element 4, so that laterally there is a longitudinally extending joint into which the side walls of the cover are immersed. A cover 6 is applied to the photoluminescent material 8 and terminates laterally with the edge of the carrier element 4. The joints between the edges of the photoluminescent material 8 and the edges of the recess 5 are filled with the projections of the cover 6. Alternatively, the photoluminescent material 9 can be cut to fit the recess 5 of the carrier element 4. In this alternative, the rectangular cover has no projections, but is glued or welded to the carrier element, for example. The gluing or welding of cover and carrier element can be carried out before or after a light strip has been arranged in the carrier element. If the luminescent strip is introduced into the hollow profile formed from cover and carrier element only after bonding or welding, this can preferably be done by introducing a silicone or polycarbonate mass containing the photoluminescent pigments.
Fig. 3A zeigt die gerade Fluchtwegmarkierung aus Fig.2, eingefügt in eine Stützform 2. Die Stützform 2 weist einen topfförmigen Körper 2a auf, in dem die gerade Fluchtwegmarkierung eingesetzt ist. Ferner weist die Stützform 2 einen Deckel 2b mit einem stempeiförmigen hervorstehenden Teil 2c auf. Der stempelartige Vorsprung 2c ermöglicht es, die Oberfläche der Fluchtwegmarkierung durch die Einwirkung der Gewichtskraft des Deckels 2b planar auszubilden. Sind die Teile 4, 6 und 8 in die Stützform 2 eingebracht, so wird die Stützform inklusive der eingebrachten Schichten auf eine Temperatur erwärmt. Vorzugsweise wird die Stützform auf eine Temperatur erwärmt, die oberhalb der Glasübergangstemperatur, jedoch unterhalb der Schmelztemperatur der verwendeten Materialien liegt. Zur Temperierung der Stützform kann ein Thermoelement in der Stützform angeordnet werden, das an oder in der photolumineszenten Masse angeordnet ist. FIG. 3A shows the straight escape route marking from FIG. 2, inserted into a support form 2. The support form 2 has a cup-shaped body 2a, in which the straight escape route marking is inserted. Furthermore, the support form 2 has a Cover 2b with a stem-shaped protruding part 2c on. The stamp-like projection 2c makes it possible to make the surface of the escape route mark planar by the action of the weight force of the lid 2b. If the parts 4, 6 and 8 are introduced into the support mold 2, the support mold including the layers introduced is heated to a temperature. Preferably, the support mold is heated to a temperature which is above the glass transition temperature but below the melting temperature of the materials used. For tempering the support mold, a thermocouple can be arranged in the support form, which is arranged on or in the photoluminescent mass.
Nach dem Erwärmen wird die Stützform 2 entweder in eine vorgefertigte Erstarrungsform gemäß Fig. 4 eingesetzt oder in eine Umformungsvorrichtung 22 gemäß Fig. 5. After heating, the support mold 2 is inserted either into a prefabricated solidification mold according to FIG. 4 or into a deformation apparatus 22 according to FIG. 5.
Fig. 3B zeigt eine alternative Ausgestaltung einer Stützform 2'. Die Stützform 2' besitzt einen topfförmigen Körper 2a', in dem die Fluchtwegmarkierung mit ihrem Trägerelement 4, dem photolumineszenten Material 8 und der Abdeckung 6 angeordnet ist. Auf der Abdeckung 6 ist ein T-förmiger Stempel 2c' angeordnet, der im dem topfförmigen Körper 2a' gehalten ist. Der T-förmige Stempel 2c' besitzt einen Stempelkopf 3 und einen Stempelstiel 5. Über zwei paarweise vorstehende Vorsprünge 7 wird der Stempfeikopf 3 in dem topfförmigen Körper 2a' gehalten. Eingesetzt werden kann der T-förmige Stempel 2c' beispielsweise indem der topfförmige Körper 2a' aufgebogen wird und der Stempel eingesetzt wird. Alternativ ist es auch möglich, den T-förmigen Stempel in den topfförmigen Körper einzuschieben. Wie in Fig. 3B dargestellt, kann der topfförmige Körper 2a' mit abgerundeten Ecken E ausgebildet sein. Abgerundete Ecken verhindern ein Einreißen der Stützform während des Biegevorganges. Bevorzugt wird für die Stützform ein Silikon mit einem möglichst großen Ein- und Weiterreißwiderstand verwendet. Fig. 3B shows an alternative embodiment of a support mold 2 '. The support mold 2 'has a pot-shaped body 2a', in which the escape route marking with its support element 4, the photoluminescent material 8 and the cover 6 is arranged. On the cover 6, a T-shaped punch 2c 'is arranged, which is held in the cup-shaped body 2a'. The T-shaped punch 2c 'has a punch head 3 and a punch stem 5. By means of two protrusions 7 projecting in pairs, the punch head 3 is held in the cup-shaped body 2a'. Can be used, the T-shaped punch 2c ', for example, by the cup-shaped body 2a' is bent and the punch is used. Alternatively, it is also possible to insert the T-shaped punch in the cup-shaped body. As shown in Fig. 3B, the cup-shaped body 2a 'may be formed with rounded corners E. Rounded corners prevent tearing of the support form during the bending process. It is preferred for the Support form uses a silicone with the largest possible tear and tear propagation resistance.
Die in Fig. 4 gezeigte, vorgefertigte Erstarrungsform 20 ist im Verhältnis zu der Stützform 2 wesentlicher stabiler ausgebildet und erlaubt vorzugsweise nur minimale Verformungsbewegungen aufgrund ihrer geringen Elastizität. Aufgrund der minimalen Elastizität kann die erwärmte Stützform 2 einfacher in die vorgefertigte Erstarrungsform 20 eingesetzt werden, so dass die Stützform 2 bei sicherem Halt und bei gleichmäßiger Fixierung abkühlen kann und die eingebrachte Fluchtwegmarkierung 4, 6, 8 erstarren kann und damit eine thermisch verformte Fluchtwegmarkierung gebildet ist. Nach dem Erstarren können die thermisch verformte Fluchtwegmarkierung 1 und die Stützform 2 aus der vorgefertigten Erstarrungsform 20 entnommen und voneinander getrennt werden. Der Vorgang des Abkühlens kann auch aktiv durch eine Kühlung, beispielsweise mit Luft, unterstützt werden. The preformed solidification mold 20 shown in FIG. 4 is substantially more stable in relation to the support mold 2 and preferably permits only minimal deformation movements due to its low elasticity. Due to the minimal elasticity, the heated support mold 2 can be more easily inserted into the prefabricated solidification mold 20, so that the support mold 2 can cool with a secure grip and with uniform fixation and the introduced escape route marking 4, 6, 8 solidify and thus formed a thermally deformed escape route marker is. After solidification, the thermally deformed escape route marker 1 and the support mold 2 can be removed from the prefabricated solidification mold 20 and separated from each other. The process of cooling can also be actively supported by cooling, for example with air.
Bei der Verwendung einer Umformungsvorrichtung 22 gemäß Fig. 5 wird die erwärmte Stützform 2 in die Umformvorrichtung 22 eingesetzt, wobei die Vielzahl an Stäben 24 zunächst entsprechend weit auseinander positioniert sind, so dass die Stützform 2 bequem in die Umformvorrichtung 22 eingesetzt werden kann. Mit dem Einsetzen der Stützform 2 in die Umformungsvorrichtung 22 können über die Steuereinheit 20 die Stäbe 24 in eine gewünschte Position verfahren werden, so dass die Stäbe 24 eine vordefinierte Verformung der Stützform definieren. Nach dem Einstellen der Stäbe 24 kann die Stützform 2 in der Umformungsvorrichtung 22 in ihrer Verformungsposition auskühlen, so dass eine Fluchtwegmarkierung 1 gemäß der durch die Stäbe 24 eingestellten Verformung gebildet wird. Nach dem Erstarren können die Stäbe 24 aus ihrer die Verformung bildende Position zurückgefahren werden, so dass die Stützform 2 bequem auf der Umform Vorrichtung 22 entnommen werden kann. Da die Stützform 2 in ihre Ausgangslage zurückkehrt, kann die geformte Fluchtwegmarkierung 1 bequem aus der Stützform 2 entnommen werden. Alternativ ist auch denkbar, dass die Stützform 2 bereits vor ihrer Erwärmung in die Umformungsvorrichtung 22 eingesetzt und erst dort erwärmt wird, bevor die Stäbe 24 in die gewünschte Verformungsposition verfahren werden. When using a forming device 22 shown in FIG. 5, the heated support mold 2 is inserted into the forming device 22, wherein the plurality of rods 24 are initially positioned correspondingly far apart, so that the support mold 2 can be conveniently inserted into the forming device 22. With the insertion of the support form 2 in the forming device 22, the rods 24 can be moved via the control unit 20 in a desired position, so that the rods 24 define a predefined deformation of the support form. After adjusting the bars 24, the support mold 2 in the forming apparatus 22 may be cooled in its deformed position so that an escape route marker 1 is formed in accordance with the deformation set by the bars 24. After solidification, the rods 24 can be moved back out of their deformation-forming position, so that the support mold 2 is conveniently removed from the forming device 22 can be. Since the support mold 2 returns to its original position, the molded escape route marker 1 can be easily removed from the support mold 2. Alternatively, it is also conceivable that the support form 2 is already used prior to its heating in the forming device 22 and only heated there before the rods 24 are moved to the desired deformation position.
Fig. 6 zeigt beispielhaft die Draufsicht einer Fluchtwegmarkierung 1 , die individuell in der Ebene verformt wurde, wobei zur Verformung die Stützform 2 in Verbindung mit der Erstarrungsform 20 gemäß Fig. 4 oder der Umformungsvorrichtung 22 gemäß Fig. 5 verwendet wurde. Die Fluchtwehmarkierung 1 gemäß Fig. 6 ist mit geschwungener Kontur ausgebildet, wobei geschwungen bedeutet, dass die Kontur der Fluchtwegmarkierung zwischen zwei entgegen gesetzten Krümmungen einen Wendepunkt aufweist. 6 shows, by way of example, the plan view of an escape route marker 1 which has been individually deformed in the plane, with the support form 2 being used for deformation in conjunction with the solidification mold 20 according to FIG. 4 or the conversion device 22 according to FIG. 5. The escape route marking 1 according to FIG. 6 is designed with a curved contour, wherein curved means that the contour of the escape route marking has a turning point between two opposite curvatures.
Die Fluchtwegmarkierung 1 ist folglich mit einfachen Mitteln herstellbar und kann zugleich mit beliebiger Form hergestellt werden. Das erfindungsgemäße Verfahren zur Herstellung der Fluchtwegmarkierung 1 ist zudem mit einfachen Mitteln umzusetzen. Ferner können die verwendeten Mittel für das Verfahren zur Herstellung für eine Vielzahl an Fluchtwegmarkierungen wiederverwendet werden. The escape route marker 1 is therefore produced by simple means and can be produced at the same time with any shape. The inventive method for producing the escape route marker 1 is also implement with simple means. Further, the means used for the method of manufacture may be reused for a variety of escape route markers.
